Simply put, digital LCD projectors are the next-generation projectors.
They’re the immediate successor of CRT projectors, a type that is slowly
being removed from the market these days. LCD pertains to the liquid
crystal display technology also used in laptops and plasma TV’s. And when

Digital LCD projectors use certain systems and chips that are not present
in CRT’s. And these are the very things that make the device compact and
portable. The chips used are quite small and they replace the cathode ray
